HARVEY PEIRCE JONES AND HARRY SLOPER JONES, OF CHICAGO, ILLINOIS, ASSIGNORS TO THE JONES PERPETUAL LEDGER COMPANY, OF SAME PLACE.

EXTENSIBLE POST FOR TRANSFER-LEDGERS, 80C.

SPECIFICATION forming part of Letters Patent No. 646,106, dated March 27, 1900. Application filed November 18, 1899. Serial No. 737,537. (No model.)

To all whom it may concern: Be it known that f we, HARVEY PEIROE JONES and HARRY SLOPER JONES, citizens of the United States, residing at Chicago, in the strong, durable, and otherwise thoroughly-l efficient construction wherein the posts may be extended according to necessity as the material to be bound accumulates. f

In the accompanying drawings our improved post is shown in its preferred form in 2o connection with the upper and lower clamp-V ing-bars of a ledgerbinder- In the drawings, Figure l is a View in elevation of the clamping-bars and ourimproved posts connected therewith, the latter being shown of two-sections height; Fig. 2, an enlarged sectional View of a post of ihree-sections height, the section being taken as indicated at line 2 of Fig. 1; Fig. V3, a perspective sectional view of one of the tubular sec- 3,0l tions employed; and Figs. t and 5, views of bolts for use in one and two section posts, respectively.

A A represent the clamping-bars, B B the extensible posts, and C a key by means of which the bar A' is clamped to the posts in any desired position through ihejmedium of any suitable or preferred mechanism contained within said barwsuch, for instance, as that described in the application of Har- 4o vey Peirce Jones, Serial No. 710,785, filed March 28, 1899.

Each post comprises, preferably, a stub a, having ascrew-bolt socket at its upper end and a collar a andshank a* at its lower end,

for irm attachment, as by screw or riveted connection, with a stub-socket in the lower frame or bar; a lower tube-section member b, supplied internally with a rigidly-secured Yshort tubeesection member b', affording at its 5o lower end a shoulder which rests upon the stub c, while the lower end of the member b is vflush with and rests upon the collar af; a tube-section member c, supplied internally with a downwardly-extending tube-section member'c, which rests on the upper end of 55 the short section b; as lmany duplicates of the tube-section c c' as may be necessary, and

screw-bolts d of the required lengths tol secure any desired number of the tube-sections together and to the stub a.. lThe tube-sections are preferably of brass,

`the outer members being firmly secured to or shrunk upon the inner members. The outer member of each tube-section above the lower one is preferably of the same length as the inner member thereof andprojects a halfvlength above said inner member. The upper end of the member b' is just a half-length below the top of the member b, and thus the sections fit together'and uponlthe stub with 7o practically continuous inner and outer surfaces of the complete built-up tube.

Each screw-bolt comprises, preferably, a steel or iron shank d', threaded at its lower end to entery the socket in the stub a, a brazen 7 5 knurled head cl2, fixed or shrunk upon the upper end of said shank, and sleeved3,v\1hich ts' tightly and rigidly on the upper end of the shank and is of such dimensions as to enter the adjacent tube-section and bear upon its inner shoulder, While a shoulder at the head bears upon the extreme upper end of said tube-section.

From the foregoing description it will be understood that posts of any number of sections within a reasonablelimit may be built up by employing the desired number of tubesections and a screw-bolt of corresponding length. The built-up post is rigidly secured and is solid throughout, and the bar A' may be clamped iirmly at any position without injury to the posts. When' it is desired to in crease the lengths of the posts, the bar A' is loosened and it and the bolts removed without disturbing the tube-sections already in 95 place. Additional tube-sections are .put in place,and longer bolts replace those first used.

The gist of our invention lies in the use of tube-sections and bolts passing therethrough to secure them to the base. It is obvious that 10o the use of internallythreaded projecting stubs as post-sockets increases the length of and thus strengthens the connection with the screw-bolts. These stubs may' be dispensed with, however, so long as the features of tubesections jointed together and to the lower bar or base and a bolt for securing and strengthening said tube-sections are preserved. The joints should be of such length as to keep the tube-sections in place while a new tube-section is being put in place.

The posts may be used in a binder or file of any description serving for securing loose leaves, papers, maps, or the like. Y

What we claim as new, and desire to secure by Letters Paten t, is-

1. In a binder of the nature described, the combination with a base and a movable clam ping-bar coperating therewith provided with a perforation, of a post received by said perforation,.comprising sleeve-sections jointed together and'to the base, and a bolt passing through said sleeve-sections'andserving to secure themtogether and bind them rgidljT` to the base, substantially as and for the pur pose set forth.

2. In abinder, the combination with a lower bar A, and an upper bar Af provided with perforations, of posts, each comprising a sleeve-section jointed to said. lower bar and provided with a socket, a sleeve-section provided at its lower end with an extension tting into said socket and provided at its upper end with asocket, and a screw-bolt for securing said sleeve-sections rmly together and binding them to said lower bar, substantially as and for the purpose set forth.

3. In a binder, the combination with a lower I bar A, and an upper bar A provided with perforations, of posts each comprising. a sleeve-section jointed to said lower bar and provided with a socket, a sleeve-section provided at its lower end with an extension tting into said socket and provided at its up'- per end with a socket, and a screw-bolt for securing said sleeve-sections firmly together and binding them to said lower bar, said screw-bolt being provided at its upper end with an enlargement fitting into the adjacent socket of a sleeve-section, substantially as and for the purpose set forth.

4t. In a binder, the combination of a bar provided with threaded bolt-sockets, sleevesections jointed to said bar at said sockets, sleeve-sections jointed together and to said irst-named sleeve-sections, screw-bolts passing through said sleeve-sections and entering said threaded sockets, and a bar movably secured to the posts thus formed, substantially as and for the purpose set forth.

5. In a binder, the combination of a bar provided with internally-threaded projecting stubs,- sleeve-sections fitting` over. said stubsandprovidedwith sockets, sleeve-sectionsfitting into said sockets of said first-- named sleeve-sections and themselves provided with socketsand screw-bolts passing through said sleeve-sections and entering'said stubs and providedfattheir upper ends with enlargements fitting the sockets of 1the upper tube-sections, purpose setforth.

6. The combination with a bar A, of lower sleeve-sections connected therewith provided Withsockets, tube-sections formed ofouterl and inner tubular members, said inner members projecting beneath the outer members to lenter said sockets, and screw-bolts for securingv said last-named sleeve-sections to said lower sleeve-sections, substantially asand for the purpose set forth.
